Fresh from the New Mexico set of The Avengers, Robert Downey Jr. made a surprise appearance alongside director Jon Favreau at the Hero Complex Film Festival in Hollywood on Sunday. In full Tony Stark beard, hair and swagger, the actor, of course, spoke about the two films that were screening, Iron Man and Iron Man 2, but also the on-the-horizon third film, Iron Man 3, which will be helmed by director Shane Black.
